The Sytong HT-66 Night Vision Add On is a light weight rear mounted night vision addon that allows you to quickly and easily convert your day scope into a state of the art night vision rifle scope for close and long range hunting day or night. A Sony CMOS Starvis 1080P sensor and OLED screen ensure higher quality viewing than its competing products.

The large internal screen of the Sytong HT-66 3.5x Digital Night Vision Rear Add On produces a high resolution and clear image of your surroundings in full colour during daytime or switch to night mode and use three levels of 850nm IR intensity with the focusable lens system to generate a clear view over hundreds of meters in complete darkness.

The supplied collar attaches to the eyepiece of your scope and allows you to quickly attach and detach the unit as the shooting conditions change, without any shift in point of impact.

The Sytong HT-66 is supplied in a presentation box complete with a carry bag and all its accessories ready to use.

    Hassle-free transaction. Highly recommended

    Great value for money! I’d recommend using this with a low power scope, 2-10x or 3-9x. The menu is easy to navigate and the image is clear enough to make a shot on a rabbit out to 80 meters with the standard IR no problem. Detection is best done with a thermal but once a target is acquired, this little unit does the business. Note it uses non-protected 18650 batteries and isn’t compatible with circuit protected 18650s.

    I’m really impressed with the clarity of this unit, I’m easily able to distinguish between cattle and deer at 200m which has already saved me a lot of walking.
    The supplied tape made it easy to fit to my scope and the menu is very easy to navigate and set up.
